In heraldry, the term star may refer to any star-shaped charge with any number of rays, which may appear straight or wavy, and may or may not be pierced. While there has been much confusion between the two due to their similar shape, a star with straight-sided rays is usually called a mullet in English heraldry while one with wavy rays is usually called an estoile.

Heraldry is a discipline relating to the design, display and study of armorial bearings, as well as related disciplines, such as vexillology, together with the study of ceremony, rank and pedigree. Armory, the best-known branch of heraldry, concerns the design and transmission of the heraldic achievement. The achievement, or armorial bearings usually includes a coat of arms on a shield, helmet and crest, together with any accompanying devices, such as supporters, badges, heraldic banners and mottoes.
The German Hyghalmen Roll was made in the late 15th century and illustrates the German practice of repeating themes from the arms in the crest. (See Roll of arms).
